Abstract: A process is proposed for producing acyloines of general formula (I) in which Ra and Rb are identical or different and represent hydrogen or a C1-C20 alkyl, a C6-C10 aryl, a C7-C12 aralkyl, a heteroaryl, or a heterocycloalkyl group, these groups being substituted if appropriate, with the exception of formaldehyde autocondensation products. In the proposed process, an aldehyde of formula (II) RaCHO is allowed to react with an aldehyde of formula (III) RbCHO, in which Ra and Rb have the meanings indicated above and at least one of the groups Ra and Rb represents a group other than hydrogen, in the presence of catalysts produced using an auxiliary base from triazolium salts of formula (IV) in which R1 and R3 are identical or different and represent aliphatic groups with 1-30 carbon atoms, or, if appropriate, aryl groups, aralkyl groups and/or heteroaryl groups, these groups being substituted if appropriate; R2 represents hydrogen or the group RbCH(OH); and A is the equivalent of a singly or multiply negatively charged anion for the electrical neutralisation of the triazolium cation charge.

Abstract: The invention relates to a method for the preparation of esters of the 3-pentene acid by which alkoxybutenes are carbonylized in the presence of a catalyst and solvent at elevated temperature and pressure. These esters are intermediate compounds for the preparation of adipinic acid, caprolactam and caprolactone. The process occurs by the reaction between at least one C1-C10-alkoxybutene where the alkoxygroup is found in allyl position to the double bond with carbon monoxide at temperatures ranging from 60 to 140 deg.C, partial pressure of the carbon monoxide from 3 to 30 MPa and in the presence of a catalyst based on palladium. 4 claims
